STUDY ON THE FLEXURAL CAPACITY OF RC BEAMS STRENGTHENED WITH NEAR SURFACE MOUNTED CFRP PLATES
-
摘要: 简要介绍近几年发展起来的表层嵌贴FRP 加固混凝土结构新技术在抗弯加固方面的研究进展;采用平截面假定导出应用这一新技术的RC 加固梁在各种破坏形式下的抗弯承载力计算公式。比较研究表明, 该计算方法与试验结果吻合良好, 可供实际加固工程参考。Abstract: It is summarized that the recent research advances on flexural strengthening with NSM FRP and presented the formula predicting flexural capacity of the failure modes with the assumption of plane section. By comparison, the predictions agree well with the experimental results, which provides a reference for practical engineering application.
